Yet, the co〆xistence of grouping and rightヽensoring poses major difficulties in regression analysis. To implement generalised linear regression of GRC counts, we derive modified Poisson estimators and their asymptotic properties, develop a hybrid line search algorithm for parameter inference, ...
The association between women’s migrant status and C-Section rates was assessed using the Poisson regression of sandwich estimation, after adjusting for possible factors. Results Of the 40,621 women included in the study, 66.9% were residents and 33.1% were internal migrants. The rate of C-...
It was also concluded that variation of elastic rock parameters like Young's modulus, Poisson's ratio and tensile strength is similar to that of the ultimate strength (Read et al., 1987). Nowadays, most of the rock engineering designs and structures are related to the transversely isotropic ...
This paper provides an EM algorithm for ML estimation of the latter model by standard software for Poisson regression. It is shown, that this algorithm can be used also to estimate the Poisson parameters of zero-inflated, zero-deflated, and standard Poisson models, when the zero observations ...
Specifically, In cases when the response or dependent variable (y) is from a count distribution, the count data regression model is employed [17,42]. One of the most used methods for modeling count data is the Poisson regression model. However, it assumes that the variance, which is a ...
A Poisson regression indicated that all explanatory variables and their 1st order interactions were highly significant. There were significant differences among bee taxa, sites and years, and their interactions (bee 脳 site; bee 脳 year; site 脳 year). Megachile species were the predominant cavity ...

A modified poisson regression approach to prospective studies with binary data. Relative risk is usually the parameter of interest in epidemiologic and medical studies. In this paper, the author proposes a modified Poisson regression a... Guangyong,Zou - 《American Journal of Epidemiology》 被引量:...
The corneal density was set to 1.4 g/mm3, Young’s modulus was 3.8 MPa, and Poisson’s ratio was 0.49. The solid mechanics physics were then added to the geometry model, which was set to a linear elastic material, while the fixed constraints and point loads were set in the model. The...
